2.1.4. Equality Flag

Try these first

1. 1.

   What does the equality flag indicate?

   Hint

   Think about comparisons in programming.

2. 2.

   What happens to the equality flag when two numbers are not equal?

   Hint

   Consider the definition of equality.

3. 3.

   What does the equality flag represent?

   • A. Overflow status
   • B. Operand equality
   • C. Sign of the result

   Hint

4. 4.

   True or False: The carry flag indicates if overflow has occurred.

   • True
   • False

   Hint

   Relate carry to exceeding limits.

5. 5.

   If you add two signed 8-bit integers whose binary representations are 11001100 and 00110011, what flags are set or reset?

   Hint

   Perform the addition and observe the binary output.

6. 6.

   How would the assembly language handle multiple comparisons using the equality flag?

   Hint

   Think about how conditional statements dictate program flow.
